GIS Software

GeoServer is an open source software server written in Java that allows users to share and edit geospatial data. Designed for interoperability, it publishes data from any major spatial data source using open standards: WMS, WFS, WCS, WPS and REST

A web based Geographic Metadata Catalog for data description and discovery. It implements international standards (e.g. ISO19115/19139, Z39.50, CSW 2.0, OGC). It originates from the United Nations and is used by many governments as geoportal software

The JTS Topology Suite is an API for modelling and manipulating 2-dimensional linear geometry. It provides numerous geometric predicates and functions. JTS conforms to the Simple Features Specification for SQL published by the Open GIS Consortium.

The Java RTree project aims to maintain an Java version of the RTree spatial indexing algorithm. See http://jsi.sourceforge.net for more information, and http://github.com/aled/jsi for latest development code.

GeoKettle is a powerful, metadata-driven spatial ETL (Extract, Transform and Load) tool dedicated to the integration of different data sources for building and updating geospatial databases, data warehouses and services.

OpenDMTP is a protocol/framework that allows communications with small devices (mobile phones, PDA's, and other high-latency/low-bandwidth devices), especially geared towards the transmission of GPS, temperature, and other remote monitoring information.

GpsPrune is a java application to view and manage coordinate data, eg from GPS units. With it you can load a variety of text and Xml formats, view the data (in 2d and 3d), edit and convert the data, correlate photos and audio, create charts and more.

ScapeToad is an easy to use application for the cartogram creation. Cartograms are deformed maps where the polygon size is proportional to a given statistical value. ScapeToad reads and writes Shapefiles.
See <https://github.com/christiankaiser/ScapeToad> for the latest version of the code.

LAnd Survey Tools "LAST" was created to preserve and expand on the work invested in an old, privately used, DOS based land survey construction and data collection application by porting much of the C++ coded logic and design concept over to Python.
